I'm uncertain. When I refer to /usr/bin/python2.3, I know I get the
system vendor's installation. When I use /usr/bin/env python2.3, I
may get something that somebody has build and which may not work
at all, or lack certain add-on packages that the script needs.
It's bad when the script works for some users but fails for others.
